package inet.networklayer.ldp;

//
// Handles and processes LDP messages.
//
// The LDP protocol is used by one LSR (Label Switched \Router) to inform
// another LSR of the label bindings it has made. The LSR uses this protocol
// to establish label switched paths through a network by mapping network layer
// routing information directly to data-link layer switched paths.
//
// Operations
//
// All LDP message types are subclassed from LDPPacket, and include
// LDPHello, LDPNotify, LDPLabelRequest, LDPIni and LDPAddress.
//
// Message processing in the LDP module is explained in
// <a href="ldp-processing.html">LDP Message Processing</a>
